“These dynamics are why loyalty’s correlation with market share remains so strong – 0.87,” Passikoff said. “Loyal customers are six times more likely to engage, repurchase, and amplify brand messaging. The bottom line: loyalty moves markets.”
Brand Keys found that even modest gains in loyalty can produce outsized financial returns.
A 5% increase in loyalty can generate up to 88% higher lifetime profits per customer, while a 2% improvement can reduce overall marketing and operational costs by as much as 29%.
